Rectangular Dielectric Resonator Antenna Fed by Graphene Films Microstrip for 5G Communication

Abstract

In this paper, a rectangular dielectric resonator antenna fed by graphene based films is presented. The antenna is compared with traditional metal antenna. The proposed antenna has a wide −10dB impedance bandwidths (3.38GHz-3.57GHz) and high peak gain of 4.52dBi at 3.5GHz in measurement. This suggests that the antenna is suitable for 5G communications at the 3.5GHz band. Radiation patterns around 3.5GHz are also presented. The results show that the proposed antenna will be a good candidate for the traditional metal antenna.
